lhremote: LinkedHelper Automation Toolkit
CLI and MCP server for LinkedHelper automation.
This project is brought to you by Alexey Pelykh.
What It Does
lhremote lets AI assistants (Claude, etc.) control LinkedHelper through the Model Context Protocol. It can:
- App management — detect, launch, and quit LinkedHelper instances
- Account & instance control — list accounts, start/stop instances, check status
- Campaign automation — create, configure, start, stop, and monitor campaigns with full action-chain management
- People import — import LinkedIn profile URLs into campaign target lists
- Profile queries — look up and search cached LinkedIn profiles from the local database
- Messaging — send direct messages, InMails, and connection requests; query messaging history and check for replies
- LinkedIn engagement — visit profiles, endorse skills, follow/unfollow, like posts, comment, and react
- Feed & post intelligence — read the LinkedIn feed, search posts, get post details, engagement stats, and engager lists
- Profile enrichment — extract emails, phones, socials, and company data from LinkedIn profiles
- LinkedIn search — build search URLs, resolve entity IDs, and query reference data for search filters
- Budget & throttle monitoring — check daily action limits and LinkedIn throttling status
- Action discovery — list available LinkedHelper action types with configuration schemas
Quick Start
Pacing: LinkedIn monitors automated activity. See the Rate Limiting guide for recommended settings.
Prerequisites
- Node.js >= 24
- LinkedHelper desktop application (requires a paid subscription)
Installation
Or run directly with npx:
Usage with Claude Desktop
Add to your Claude Desktop configuration (claude_desktop_config.json):
Once configured, Claude can use every registered tool directly. A typical workflow:
find-app— Detect a running LinkedHelper instance (orlaunch-appto start one)list-accounts— See available LinkedIn accountsstart-instance— Start an instance for an accountdescribe-actions— Explore available action typescampaign-create— Create a campaign from YAML/JSON configurationimport-people-from-urls— Import target LinkedIn profiles into the campaigncampaign-start— Run the campaigncampaign-status/campaign-statistics— Monitor progressquery-messages/check-replies— Review messaging results
CLI Usage
The lhremote command provides the same functionality as the MCP server. Every MCP tool has a corresponding CLI command except where its reference section says otherwise.

Common Parameters
Most tools and CLI commands connect to LinkedHelper via the Chrome DevTools Protocol (CDP). In addition to the tool-specific parameters listed below, CDP-connected tools accept the following, except where a tool's own reference section says otherwise. The Default column describes the MCP tools; each CLI command exposes its own subset of these flags, and the notes below give the differences that matter:
| Parameter | CLI Flag | Type | Default | Description |
|---|---|---|---|---|
cdpPort | --cdp-port | number | auto-discovered | CDP debugging port |
cdpHost | --cdp-host | string | 127.0.0.1 | CDP host address |
allowRemote | --allow-remote | boolean | false | Allow connections to non-loopback addresses |
accountId | varies — see below | number | auto-select if single account (MCP) | LinkedHelper account to act as |
cdpPort is discovered, not defaulted. Omit it and lhremote finds the port of the running LinkedHelper itself, whatever that port happens to be; it raises LinkedHelperNotRunningError or LinkedHelperUnreachableError when no instance is reachable. Pass a port only to target one specific instance — you do not need one to reach a LinkedHelper that is not on 9222. Two exceptions: quit-app takes cdpPort alone (no cdpHost, allowRemote or accountId) and does default to 9222; and a port is required whenever cdpHost is non-loopback, because discovery scans local processes only.
accountId is required once more than one account is configured. With a single account the MCP tools resolve it themselves; with several they cannot, and the call fails — most raise AccountResolutionError, while start-instance and stop-instance answer with their own message. Either way, list-accounts gives you the ID. Every tool that connects to a running LinkedHelper accepts accountId; the ones that do not are the app-management tools (find-app, launch-app, quit-app), which act on the application rather than on an account, the reference tools (build-linkedin-url, resolve-linkedin-entity, list-linkedin-reference-data, describe-actions), which open no connection, and the profile-cache readers (query-profile, query-profiles, query-profiles-bulk), which search every account's local database and cannot be scoped to one. The CLI never auto-resolves, at any account count: start-instance / stop-instance take a required positional <accountId>, comment-on-post / react-to-post take --account-id, and no other command exposes it.
Security warning: Enabling
allowRemotepermits CDP connections to remote hosts. CDP is an unsandboxed protocol that grants full control over the target browser — equivalent to remote code execution. Only enable this when the network path between your machine and the target host is fully secured (e.g., SSH tunnel, VPN, or trusted LAN).

cdpPort | number | No | auto-discovered | CDP port |
unfollow-profile
Unfollow a LinkedIn member profile or organization page by navigating to it and clicking the Following → Unfollow toggle. Accepts both profile URLs and company URLs — LinkedIn renders the same Follow/Following toggle on both surfaces. Prefer this over unfollow-from-feed for bulk feed-hygiene workflows: feed-based tools are limited to one action per feed fetch because the feed DOM refreshes after each hide/unfollow, invalidating other indexes; this tool works regardless of whether the author is currently in the home feed. For org-level feed-volume escalation it is also the substitute for a mute, since LinkedIn does not expose a Mute action on company pages. Returns the detected prior follow state and target kind (profile vs company), so bulk workflows can distinguish actual unfollows from no-op calls on already-unfollowed targets and from inaccessible targets (private/blocked profiles, restricted/unavailable companies). Unlike follow-person with mode: unfollow, which runs an ephemeral campaign and deducts from the daily action budget, this acts on the page directly and does not.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
profileUrl | string | Yes | — | LinkedIn profile URL (e.g. https://www.linkedin.com/in/{publicId}/) or company URL (e.g. https://www.linkedin.com/company/{slug}/) |
dryRun | boolean | No | false | When true, detects the follow state but does not click Unfollow (the dialog is opened and dismissed) |

Feed & Posts
get-feed
Read the LinkedIn home feed. Returns structured post data with cursor-based pagination.
| Parameter | Type | Required | Default | Description |

cursor | string | No | — | Cursor token from a previous call for the next page |
cdpPort | number | No | auto-discovered | CDP port |
get-post

get-post-stats
Get engagement statistics for a LinkedIn post: reaction count (broken down by type), comment count, and share count.
| Parameter | Type | Required | Default | Description |

cdpPort | number | No | auto-discovered | CDP port |
get-post-engagers
List people who engaged with a LinkedIn post (reacted, etc.) with their profile info and engagement type. Supports pagination. Returns a shortfall field alongside the engagers: null when no reaction count the page rendered contradicted what was collected — the absence of a contradiction, not a guarantee of completeness — otherwise a record of how many rows were collected, how many were asked for, the reaction count the page itself rendered, and why collection stopped. paging.total carries the page's own reaction count where that was readable and falls back to the number of rows collected where it was not — the pre-pagination count, not the length of the returned slice, so with start > 0 it can exceed the rows you got back. Either way it is not an independent answer to whether more exist. MCP tool only — no CLI command.

| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
feedIndex | number | Yes | — | Zero-based index of the post in the visible LinkedIn feed (pair with get-feed to identify posts) |
dryRun | boolean | No | false | When true, locates the menu item but does not click it |

hide-feed-author-profile
Mute a LinkedIn profile's posts in the home feed by navigating to the profile page and invoking Mute {Name} from the More menu. Prefer this over hide-feed-author for bulk feed-hygiene workflows: feed-based tools are limited to one action per feed fetch because the feed DOM refreshes after each hide/unfollow, invalidating other indexes. Works regardless of whether the author is currently in the feed. Returns structured results: success when muted; { success: false, reason: "mute_not_available" } for non-connections or profiles where Mute is not exposed; { success: false, reason: "already_muted" } when the profile is already muted. LinkedIn exposes no Mute action on company pages; use unfollow-profile for an organization.
| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
profileUrl | string | Yes | — | LinkedIn profile URL (e.g. https://www.linkedin.com/in/{publicId}/) |
dryRun | boolean | No | false | When true, opens the More menu and detects mute availability but does not click Mute |

unfollow-from-feed

| Parameter | Type | Required | Default | Description |
|---|---|---|---|---|
feedIndex | number | Yes | — | Zero-based index of the post in the visible LinkedIn feed (pair with get-feed to identify posts) |

Known Limitations
- Platform support: LinkedHelper runs on macOS, Windows, and Linux. Binary paths are detected automatically but can be overridden with the
LINKEDHELPER_PATHenvironment variable. - Instance startup time: Starting an instance loads LinkedIn, which may take up to 45 seconds.
- Profile data is cached:
query-profileandquery-profilessearch the local LinkedHelper database. Profiles must have been visited or imported by LinkedHelper to appear in results. - Messaging scrape is slow:
scrape-messaging-historynavigates LinkedIn's messaging UI and can take several minutes depending on conversation volume. - Same-machine requirement: lhremote must run on the same machine as LinkedHelper. CDP connections are localhost-only by default (for security), and database access requires direct file system access to the LinkedHelper SQLite database.
Troubleshooting
LinkedHelper is not running
Error: LinkedHelper is not running (no processes found) — or LinkedHelper is not running (no CDP endpoint at port <port>) when you named a port explicitly.
Solution: Use launch-app to start LinkedHelper, or start it manually. lhremote communicates with LinkedHelper via the Chrome DevTools Protocol (CDP), which requires the application to be running. The second form means nothing answered on the port you named: drop --cdp-port and lhremote will discover the running instance's port itself.
LinkedHelper is unreachable
Error: LinkedHelper processes detected but CDP endpoint is unreachable
Solution: LinkedHelper is running but its CDP port is not responding. This typically means a stale or zombie process. Use launch-app --force to kill stale processes and relaunch, or manually restart LinkedHelper.
Application binary not found
Error: LinkedHelper application binary not found. Set LINKEDHELPER_PATH to override.
Solution: Install LinkedHelper from linkedhelper.com. If installed in a non-standard location, set the LINKEDHELPER_PATH environment variable to the binary path.
No accounts found
Error: No accounts found.
Solution: Open LinkedHelper and configure at least one LinkedIn account before using lhremote.
Multiple accounts found
Error: Multiple accounts found. Specify accountId. Use list-accounts to see available accounts.
Solution: Use list-accounts to see available accounts, then pass the desired accountId to start-instance, stop-instance, or other tools.
No instance running
Error: No LinkedHelper instance is running. Use start-instance first.
Solution: Run start-instance before using campaign or messaging tools. An instance must be running to interact with LinkedIn.
Instance initialization timeout
Error: Instance started but failed to initialize within timeout.
Solution: The instance was started but took too long to finish loading. This can happen on slow connections. Try again; the instance may still be starting in the background. Use check-status to verify.
Database not found
Error: No database found for account
Solution: The LinkedHelper database file is missing for the specified account. Ensure the account has been used at least once in LinkedHelper so that a local database has been created.
